Find the total number of structural isomers (ignoring stereoisomers) possible for the alkane with th — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

For $C_6H_{14}$, DU = 0, indicating an open-chain saturated alkane. The structural skeletons are: 1) A straight chain of 6 carbons (n-hexane). 2) A 5-carbon chain with a methyl group at C2 (2-methylpentane). 3) A 5-carbon chain with a methyl group at C3 (3-methylpentane). 4) A 4-carbon chain with two methyls at C2 (2,2-dimethylbutane). 5) A 4-carbon chain with methyls at C2 and C3 (2,3-dimethylbutane). Total structural isomers = 5.
